If your machine can boot from cd then you can boot a live cd of backtrack. Your asking to boot a cd to make your usb boot and that doesnt make sense. call me crazy but why would you do that.........Tell me somthing I dont know because I love to learn and I am often wrong.

i had the same problem, what i did is make a dos boot disk an include my usb dos drivers(USBASPI.SYS,ASPIDISK.SYS) then i added a line in my autoexec.bat so it ran bt/boot/dos/loadlin or you could just load it from any dos prompt if you have usb drivers loaded.

I often install and change stuff on "my"-BackTrack, almost every time I use BT.
My configs/installed-software would be gone if I start the live-CD, wouldn't they?

Download "wakepup" which is a program for booting puppy linux.
Click on Wakepup an you should be prompted for a formated disk etc..
Go into the disk you just made and delete everything in autoexec.bat and config.sys then add these change drive letters accordingly

autoexec.bat

c:
cd boot\dos
bt

and i added this to config.sys

!switches=/E

!device=A:\driver\usb\USBASPI.SYS /v

!device=A:\driver\ASPIDISK.SYS

!SHELL=A:\COMMAND.COM A:\ /E:1024 /F /MSG /P=A:\AUTOEXEC.BAT

!files=20
!buffers=20
!lastdrive=Z

Make sure you load the correct drivers they may not be the same as above.
